Would any seasoned Birkenstock wearers be able to give an opinion on the fit of my Madrids? These are the 37 narrow. Usually I wear a size 5/ EU38 but was advised to size down but I can't work out if these are too small or not! Toes aren't touching the front but are very close. Also wondering if I should go for the Arizona instead of the Madrid! Thanks in advance and apologies for the foot pics!
